3-1207UDS1-BD (UDS1 Interface Circuit Pack)

1 FAIL The test failed. The UDS1 interface circuit pack detected a loss of multiframe

alarm (LMA). An out of frame condition occurred on the UDS1 interface circuit

pack. The UDS1 interface circuit pack will transmit a remote multiframe alarm

(RMA) to the remote UDS1 endpoint until the LMA is retired.

If the UDS1 connects to a T1 network facility or to another switch, do the

following:

1. Verify that both endpoints of the DS1 link are administered using the same

signaling mode, framing mode, and line coding.

2. Contact T1 Network Service or a technician at the far-end switch to

diagnose the remote DS1 endpoint.

3. Check the physical connectivity of the UDS1 packs and of the cable.

4. Replace the local UDS1 interface circuit pack, and repeat the test.

If the UDS1 connects to a line-side terminating device (for example, a PRI

terminal adapter), do the following.

1. Verify that the switch DS1 and the line-side terminating device are

administered using the same signaling mode, framing mode, and line

coding.

2. Investigate the maintenance status of the line-side terminating device.

Refer to the ’Line-Side Terminating Device Operating Manual’ for

information.

3. Contact the vendor of the line-side terminating device to diagnose the

equipment.

4. Check the physical connection of the UDS1 interface circuit pack to the

terminating device, and check the premise distribution system (or the

intra-premise wiring) for physical connection failures.

5. Replace the local UDS1 interface circuit pack and repeat the test.
